The Instagram star puts her incredible appearance down to healthy eating and gym routine.

Speaking to the Daily Mail, Jessica said "'I used to eat Nutella by the spoonful, and on my toast and on my bananas... That's when things started getting REALLY out of hand with my body composition and finally prompted me to change my daily habits.'

She also revealed that she doesn't have an insane workout plan, explaining she just goes to the gym three times a week.

Jessica said "I also know if there’s a will there’s a way. It’s been an adjustment for us, but it’s working really well for now. I always say, 'You do what you can!' Be strict about your goals & flexible on how to achieve them."
